We now offer our 3 Inch Universal XPipe (1.25" Pipe Spacing) for those looking to design their own exhaust from the ground up. These are perfect for anyone who wants to avoid the stamped style X-Pipe, which can sometimes be a bottleneck in a free flowing exhaust. Our X-Pipe features 1.5mm thick piping in 304 stainless steel that is brushed and then slightly polished. This offers a more finished look over flat brushed. Each pipe is mandrel bent to avoid any restrictions in flow. We cut each pipe using precision CNC machinery and then deburr before fully TIG welding. To keep the pipes from having a burned look around the welded area, we avoid double welding. Instead, we overlap more welds on one pass to increase the strength. Each X-Pipe will have a different oxidation color to the welds due to the chromium content in 304, giving each of our X-Pipes a one of a kind look. Lightweight brackets have also been TIG welded between both pipes to completely eliminate stress on the center weld during shifting.

    Unmatched quality and design

    I was very specific in hunting down an X pipe for my 16 Sierra 1500. It’s extremely low, still 4x4 and can only be routed a certain way. Finding the Project Exhaust 3” X Pipe was the PERFECT fit for how I was running the exhaust. The quality is hands down the best, and I’m sad it’s completely unseen. Shipping was quick and a nice quick email thanking me for the purchase really set the support in stone for me. Do not hesitate to buy from and support Project Exhaust! Thank you!

    Awesome X-Pipe

    I purchased my X-Pipe from project exhaust because the dimensions matched the needs of my custom exhaust on my Godzilla 7.3 Mustang. The craftsmanship and quality were outstanding. Such a welcome treat when ordering something sight unseen and no prior knowledge of their products. I would definitely recommend Project Exhaust products!
